Description

Technical Field

[0001] The utility model belongs to the technical field of grinding machine equipment and relates to a single-beam five-axis rough and fine grinding structure. Background Art

[0002] At present, general linear rail grinding machines achieve rough grinding and fine grinding by dressing the grinding wheel. Because the grinding wheel number used for grinding is the same, that is, the same grinding wheel is used for rough grinding and fine grinding. However, during the rough grinding stage, the grinding wheel is subjected to higher grinding forces and heat loads, which can easily cause the grinding wheel surface to wear or clog. When the same grinding wheel is used for fine grinding, the worn and clogged surface cannot provide the required surface finish and precision, which in turn affects the final quality of the parts. In addition, fine grinding requires the grinding wheel to have sharp abrasive grains and an open structure to ensure high precision and surface quality, while the grinding wheel may become passivated after rough grinding, affecting grinding efficiency and processing speed.
